Description
Technical field
A kind of flood control command based on grid of the present invention studies and judges system.
Background technology
Measures against flood disaster mainly includes engineering measure and non-engineering measure.Engineering measure is due to aobvious in flood control and disaster reduction
Benefit is write, is unanimously favored by people, each state all spares no effort to build the flood control works such as dyke, reservoir, improve flood control mark
It is accurate.But it is on the one hand huge flood control works fund input, is on the other hand but that the big flood occurrence frequency for being difficult to contain increases, flood
Disaster loss loses the lasting trend for rising.Non-engineering flood control be exactly by flood forecasting, Flood Control Dispatch, flood diversion, flood detention, legislation,
The non-engineering measures such as flood insurance, floodplain management reduce disaster or mitigate the loss that disaster may be brought.Flood control command decision-making
Support system is the integrated system of various non-engineering flood controls, and it is with computer technology, network communications technology and remote sensing technology
Deng based on, by the automatic data collection to various flood control information, real-time Transmission, comprehensive analysis and Intelligent treatment, in time, correctly
Implement emergency flood fighting disaster relief command scheduling.For effectively mitigating Flood Damage, assure the safety for life and property of the people, have
Important meaning.
Overwhelming majority flood control command decision system is based on GIS platform constructions at present, real with WEBGIS as integrated framework
The functions such as existing flood control related display, inquiry, editor, thematic charting, the map publishing of spatial data.GIS platforms include two dimension
GIS platforms and three-dimension GIS platform.
Two-dimension GIS platform possesses general GIS functions, based on geography information, by hydraulic engineering information management
Related service is combined with GIS technologies, realizes management and displaying to space and attribute data.Specific requirement includes：Support
Shape files data forms, while supporting grating image form, such as BMP, GIF, PNG, JPEG；Map can be entered
The operations such as row amplifies, reduces, roaming, selection；Figure layer control can be carried out and dynamic layer is realized, thematic maps can be generated；
Corresponding click can be carried out to map to inquire about, draw the operations such as frame inquiry, arbitrary polygon inquiry；Map can be looked into by object
Ask, realize the positioning and flashing function of object, while the spatial measuring functions such as range finding can be realized.It is geographical in three-dimension GIS platform
Information realistic looking representation in the way of three-dimensional, and hydraulic engineering information management related service is combined with three-dimensional data,
The management and displaying to space and attribute data are realized, the depth and range of Information application is improved.
Current flood control command DSS major function mainly includes duty management, flood situation letter under daily state
Under report, information on duty, fax managing, short message managing and emergency rating（During typhoon, heavy rain）The flood control being the theme with disaster
Consultation, windproof consultation, anti-consultation.In case as a example by platform consultation major function be included in GIS map be superimposed the real-time rain condition of displaying,
Real Time Hydrologic, real-time landscape, typhoon track, real-time work feelings, video information, emergency team 5, flood fighting materials, keep away calamity place；Check
Real-time statistical report, check reception fax, carry out short message sending；Consultation management can be carried out, consultation material is automatically generated；Can
Urban waterlogging situation is understood in real time, checks city inland river water level, urban water conservancy project work feelings information.
Current technology is primarily present following shortcoming：
（1）Based on GIS platform flood control command decision system in emergency rating commanding and decision-making, can only often be paid close attention to administrative region
The details in overall distribution information or point on big face, but Disaster Event during disaster is frequently experienced in necessarily
Regional extent, therefore the flood control command decision system based on GIS platform can not targetedly be analyzed, commanded and be ground
Sentence.
（2）Due to information and the upper information of point on integral face can only be presented based on GIS flood control commands decision system, thus fail to
Carry out the Analysis of Networking of associated point, cell turned to grid, can carry out relevant information in cell association, contrast and
Present.
（3）Consultation during hazard weather is, it is necessary to grasp history, present and following information, overwhelming majority system is equal at present
The dynamic grasp of real time information can be realized, the rainfall and flood forecasting for future often exist due to the limitation of objective condition
Certain deviation, and historical information as determination information often for disaster during study and judge with vital effect, at present
Existed system is often simply simply enumerated to historical summary, and failing intelligence carries out similarity analysis, is that user is presented phase
Seemingly spend the historical flood data with reference significance high.
The content of the invention
The purpose of the present invention is directed to above weak point, there is provided a kind of flood control command based on grid studies and judges system,
